A key component of SteamVR isn't working properly. (301)

[Futaba Sakura]

What the hell is going on?? I've had my Quest 2 since January, and with a link cable SteamVR has never had any real issues on my PC until now. I have an RTX 3060 Ti, I'm pretty sure none of the software on both my headset and my PC are out of date, and I'm also pretty sure I don't own any of the devices or software Steam claims to conflict with the VR stuff. So what's the issue?? I genuinely want to know, because I'm so frustrated with this and I really don't want to go through a tedious troubleshooting cycle.

It is happening to me too, I dont use a link cable, so probably that is not the problem.
Using it since December without any type of error till this last week.
